Cucurbita Linn. vegetables have a long history of cultivation and have been cultivated all over the world. With the increasing area of saline–alkali soil, Cucurbita Linn. is affected by salt stress, and calmodulin-binding transcription activator (CAMTA) is known for its important biological functions. Although the CAMTA gene family has been identified in several species, there is no comprehensive analysis on Cucurbita species. In this study, we analyzed the genome of Cucurbita maxima and Cucurbita moschata. Five C. moschata calmodulin-binding transcription activators (CmoCAMTAs) and six C. maxima calmodulin-binding transcription activators (CmaCAMTAs) were identified, and they were divided into three subfamilies (Subfamilies I, II, and III) based on the sequence identity of amino acids. CAMTAs from the same subfamily usually have similar exon–intron distribution and conserved domains (CG-1, TIG, IQ, and Ank_2). Chromosome localization analysis showed that CmoCAMTAs and CmaCAMTAs were unevenly distributed across four and five out of 21 chromosomes, respectively. There were a total of three duplicate gene pairs, and all of which had experienced segmental duplication events. The transcriptional profiles of CmoCAMTAs and CmaCAMTAs in roots, stems, leaves, and fruits showed that these CAMTAs have tissue specificity. Cis-acting elements analysis showed that most of CmoCAMTAs and CmaCAMTAs responded to salt stress. By analyzing the transcriptional profiles of CmoCAMTAs and CmaCAMTAs under salt stress, it was shown that both C. moschata and C. maxima shared similarities against salt tolerance and that it is likely to contribute to the development of these species. Finally, quantitative real-time polymerase chain reaction (qRT-PCR) further demonstrated the key role of CmoCAMTAs and CmaCAMTAs under salt stress. This study provided a theoretical basis for studying the function and mechanism of CAMTAs in Cucurbita Linn.

Malate dehydrogenase (MDH) is widely distributed in plants and animals, and plays an important role in many metabolic processes. However, there have been few studies on MDH genes in poplar. In this study, 16 MDH gene sequences were identified from the Populus trichocarpa genome and renamed according to their chromosomal locations. Based on phylogenetic analysis, the PtMDH genes were divided into five groups, and genes that grouped together all shared the same subcellular location and had similar sequence lengths, gene structures, and conserved motifs. Two pairs of tandem duplication events and three segmental duplication events involving five genes were identified from the 15 PtMDH genes located on the chromosomes. Each pair of genes had a Ka/Ks ratios <1, indicating that the MDH gene family of P. trichocarpa was purified during evolution. Based on the transcriptome data of P. trichocarpa under salt stress and qRT-PCR verification, the expression patterns of PtMDH genes under salt stress were analyzed. The results showed that most of the genes were upregulated under salt stress, indicating that they play a role in the response of poplar to salt stress. The PtmMDH1 gene can be used as an important salt-tolerant candidate gene for further investigations of molecular mechanisms. This study lays the foundation for functional analysis of MDH genes and genetic improvement in poplar.

Abstract Background: Pumpkin is an important non-saline economic vegetable, salt stress often restricts the growth of pumpkin roots and the transportation and balance of mineral ions in the body. Oligopeptide transporter (OPT) plays an important role in transporting small peptides, secondary amino acids, Glutathione and minerals. However, information about the family of OPT in pumpkin is still limited. Results: In this study, 45 OPT transporters were identified from two cultivated species of Cucurbita moschata and Cucurbita maxima. Phylogenetic analysis showed that these OPT families were divided into two evolutionary branches: OPT clade and yellow stripe-like (YSL) clade. All of these genes contain the typical structure of OPT superfamily, OPT clade contains 12 conserved motifs, while the YSL clade contains 7 conserved motifs. There are tandem gene replication events on chromosomes 13, 16 and 18 of Cucurbita moschata and Cucurbita maxima, and 17 and 18 pairs of genes were collinear with Arabidopsis thaliana, respectively. Promoter element analysis showed that there were many cis-acting elements in the upstream promoters of these genes in Cucurbita moschata and Cucurbita maxima, which responded to 10 kinds of stress, especially hormones (MeJA and ABA) and hypoxia. The expression patterns based on transcriptome data sources showed that some OPT genes were organ-specific and tissue-specific, which might be involved in plant functional development. Transcriptome and qRT-PCR verification tests showed that CmoYSL7, CmaOPT15 and CmaYSL7 of Cucurbita moschata and Cucurbita maxima might play a key role in regulating the balance of metal ions between leaf mesophyll and leaf veins under salt stress. Conclusions: Overall, the data obtained from our study contribute to a better understanding of the complexity of the OPT genes family in pumpkins. These results will provide new insights into the mechanism of salt tolerance and the structure and function of OPT genes in pumpkin.

Abstract Background: Plant calmodulin-binding transcription activator (CAMTA) proteins play important roles in hormone signal transduction, developmental regulation, and environmental stress tolerance. However, in wheat, the CAMTA gene family has not been systematically characterized. Results: In this work, 15 wheat CAMTA genes were identified using a genome-wide search method. Their chromosome location, physicochemical properties, subcellular localization, gene structure, protein domain, and promoter cis-elements were systematically analyzed. Phylogenetic analysis classified the TaCAMTA genes into three groups (groups A, B, and C), numbered 7, 6, and 2, respectively. The results showed that most TaCAMTA genes contained stress-related cis-elements. Finally, to obtain tissue-specific and stress-responsive candidates, the expression profiles of the TaCAMTAs in various tissues and under biotic and abiotic stresses were investigated. Tissue-specific expression analysis showed that all of the 15 TaCAMTA genes were expressed in multiple tissues with different expression levels, as well as under abiotic stress, the expressions of each TaCAMTA gene could respond to at least one abiotic stress. It also found that 584 genes in wheat genome were predicted to be potential target genes by CAMTA, demonstrating that CAMTA can be widely involved in plant development and growth, as well as coping with stresses. Conclusions: This work systematically identified the CAMTA gene family in wheat at the whole-genome-wide level, providing important candidates for further functional analysis in developmental regulation and the stress response in wheat.

Pumpkin (Cucurbita moschata) is an important cucurbit vegetable crop that has strong resistance to abiotic stress. While heat shock protein 20 (HSP20) has been implicated in vegetable response to heat stress, little is known regarding activity of HSP20 family proteins in C. moschata. Here, we performed a comprehensive genome-wide analysis to identify and characterize the functional dynamics of the Cucurbita moschata HSP20 (CmoHSP20) gene family. A total of 33 HSP20 genes distributed across 13 chromosomes were identified from the pumpkin genome. Our phylogenetic analysis determined that the CmoHSP20 proteins fell into nine distinct subfamilies, a division supported by the conserved motif composition and gene structure analyses. Segmental duplication events were shown to play a key role in expansion of the CmoHSP20 gene family. Synteny analysis revealed that 19 and 18 CmoHSP20 genes were collinear with those in the cucumber and melon genomes, respectively. Furthermore, the expression levels of pumpkin HSP20 genes were differentially induced by heat stress. The transcript level of CmoHSP20-16, 24 and 25 were down-regulated by heat stress, while CmoHSP20-7, 13, 18, 22, 26 and 32 were up-regulated by heat stress, which could be used as heat tolerance candidate genes. Overall, these findings contribute to our understanding of vegetable HSP20 family genes and provide valuable information that can be used to breed heat stress resistance in cucurbit vegetable crops.

Under abiotic stress, TaCAMTA1, 3, and 6 were up-regulated after drought treatment, while the expression levels of TaCAMTA1 and 3 were induced after cold treatment, indicating that they may be involved in drought and cold stress response. This work systematically identified the CAMTA gene family in wheat at the whole-genome-wide level, providing important candidates for further functional analysis in developmental regulation and the stress response in wheat.

Inducible Genes

Androgen-inducible genes (AIGs), which can be regulated by androgen level, constitute a group of genes characterized by the presence of the AIG/FAR-17a domain in its protein sequence. Previous studies on AIGs demonstrated that one member of the gene family, AIG1, is involved in many biological processes in cancer cell lines and that ADTRP is associated with cardiovascular diseases. It has been shown that the numbers of AIG paralogs in humans, mice, and zebrafish are 2, 2, and 3, respectively, indicating possible gene duplication events during vertebrate evolution. Therefore, classifying subgroups of AIGs and identifying the homologs of each AIG member are important to characterize this novel gene family further. In this study, vertebrate AIGs were phylogenetically grouped into three major clades, ADTRP, AIG1, and AIG-L, with AIG-L also evident in an outgroup consisting of invertebrsate species. In this case, AIG-L, as the ancestral AIG, gave rise to ADTRP and AIG1 after two rounds of whole-genome duplications during vertebrate evolution. Then, the AIG family, which was exposed to purifying forces during evolution, lost or gained some of its members in some species. For example, in eutherians, Neognathae, and Percomorphaceae, AIG-L was lost; in contrast, Salmonidae and Cyprinidae acquired additional AIG copies. In conclusion, this study provides a comprehensive molecular phylogenetic analysis of vertebrate AIGs, which can be employed for future functional characterization of AIGs.
